Description

The Trion 28 Black is a backpack from the brand Mammut designed for mountaineers and enthusiasts of ski touring and climbing.

This lightweight and sturdy pack is made from abrasion-resistant materials. Its very practical carrying system, consisting of elastic straps and a padded waist belt, ensures you enjoy optimal comfort and a perfect fit. This versatile pack is made water-resistant thanks to a durable PFC-free water-repellent coating, which will particularly appeal to environmentally conscious mountaineers, with its bluesign® certification and its material partially made from recycled fibres.

On the practical side, the Trion 28, created in collaboration with professional mountaineers Stephan Siegrist and Nico Hojac, features multiple easily accessible compartments. Among these, you will find a main compartment accessible via a roll-top zip opening or a side opening, mesh pockets on the shoulder straps, a compartment to store avalanche equipment, as well as a water-repellent zipped external pocket. Additionally, two robust ice axe holders, a pole holder, a reinforced ski carry, and another attachment point for fixing a rope on the flap complete this ideal setup. Finally, this backpack is compatible with your preferred hydration system.
